DEDRA DED1594S40 drill hole saw

The Dedra DED1594S40 diamond cutting disc is a vacuum-brazed, 40 mm diameter blade with an M14 arbor thread designed for high-precision cutting and trimming of hard materials. Its small diameter and vacuum-brazed diamond edge provide a durable cutting surface that maintains sharpness during detail work. The disc is compatible with angle grinders and rotary tools that accept an M14 threaded arbor, and is intended for tasks requiring accuracy and minimal material removal.

Advantages

The vacuum-brazed (VB) diamond edge offers long-lasting cutting performance and consistent edge retention on hard, abrasive materials. The compact 40 mm diameter enables precise control in confined areas and for fine trimming. The M14 thread ensures direct mounting to many common grinders and rotary tools without additional adapters. The rigid metal body supports stable operation and reduces vibration during light cutting and finishing jobs.

Suitable for

• Precision cutting and trimming of ceramic tiles
• Small-scale stone shaping and detailing
• Ceramic and porcelain edge finishing
• Detail work on granite, marble, and other natural stone

Key specifications

• Disc diameter: 40 mm
• Arbor/thread: M14
• Edge type: vacuum-brazed diamond
• Body material: metal with diamond-coated rim
• Intended use: dry cutting for detail and precision tasks

How to use

Fit the disc onto a compatible grinder or rotary tool with an M14 threaded arbor and secure it according to the tool manufacturer's instructions. Operate the tool at the recommended speed range for small diamond discs, applying light, steady pressure and allowing the abrasive edge to cut without forcing. For best accuracy, position the workpiece securely and make controlled passes. Periodically inspect the disc for wear, overheating, or clogging and stop the tool before making adjustments or changing the accessory.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, dust mask, and hearing protection. For ceramics and stone, ensure adequate dust extraction or wetting where possible to reduce airborne dust. Avoid excessive lateral pressure and overheating; allow the diamond edge to work progressively for longer life and better results.
